Ladbrokes make Michael Carberry an odds-on chance to make his Ashes debut when the first Test gets underway in Brisbane on 21st November.
His score of 153 against Australia 'A' came on the back of a half-century in England's opening match and he has been installed as 1/6 favourite to open alongside Alastair Cook.
Joe Root, who is now widely expected to bat in the middle order, is available at 4/1.
Left-hander Carberry is 7/2 to hit a century at the Gabba and has been cut from 20/1 to 7/1 to be England's leading run-scorer in the series.
"Carberry's in fine form and at this stage it's hard not to see him opening up with Cook in Brisbane," Ladbrokes cricket betting expert Jessica Bridge said.
